Comment:
Because it did not even occur to me that the right hand side could have
more than one. Thanks for pointing that out.
I let b, the right hand side, have more columns.
I fixed a bug that is in apparently dead code and wouldn't matter even if
it wasn't.
I made a branch for this ticket because that seems to be the proper way to
do things here.
Also it seems like for non-square matrices the RDF/CDF right_solve and
left_solve could just lean on the generic right_solve and left_solve? (The
scipy solver needs square matrices, so right now the RDF/CDF code rejects
them.) Anyway that would be for a different ticket if it even matters.
